I cannot give you the exact time in Britain right now. This is because the time is constantly changing.
To find out the current time in Britain, I recommend using a search engine like Google, Bing, or DuckDuckGo and searching for "time in Britain" or "time in UK". These search engines will display the current time based on your location and the time zone of Britain (which is usually Greenwich Mean Time (GMT) or British Summer Time (BST), depending on the time of year).
